Customer Question

I have a Onan generator. Model no.4KYA26100K. Serial no., E070058929.
Generator starts right up, then quits after about 10 mins. I checked when this happened the first time and found it was low on oil. Added prob a cup of ww 40. The same thing continues, and will start up again for in a few mins, like 15-30 mins. What can be cause? Have had Motorhome 8 yrs and never a problem. Thanks

An issue like this is usually a bad magneto, bad coil, or a bad fuel pump.
